unlike all the peopel that run without a cat, i run with a cat, just no muffler, unless i need to have it inspected, then the muffler goes back on... my muffler has a welded sleeve on it, and a muffler clamp attached to the muffler, so its pretty much slide it on, hang the muffler up, and clamp it down.....
my cat has a port on the side for a probe, and my truck has a temp probe, but i have heard its fine to run without it.
muffler has a turndown
how loud is that without a muffler? i might have to run mine with no muffler for a couple days and was just curious....
